Yeah, I installed the truck-lite on my Monster, the difference is pretty damn fantastic.
I do have one small issue with it, and that's the beam is so focused that when I lean into a turn, the beam dips out of my sight line, which at first was a little disconcerting. It might be due to the headlight angle (Maybe I have it pointed down too much or something), but I noticed that when I had it aimed higher I would get a lot more people flashing me with their lights because they thought my brights were on. Once I lowered it a little the flashing from cars stopped.
